DURHAM, N.C. – A total of 17 Duke players are currently playing baseball this summer, including two-way sophomore pitcher Marcus Stroman who is representing the country on the USA Baseball Collegiate National Team.

Stroman is off to a dominant start with Team USA, striking out all seven batters he’s faced this summer. He struck out the side in order in consecutive appearances over the last two days and is now less than one week away from leading Team USA into its five-game series with Japan on July 3-8.
